Our 757's seat 188 and our 321neo will have 196 on it. Even if they have to block some seats on specific flights that helps...plus the fuel burn is way down and after 20 years airframe maintenance on the 75/76 skyrockets.
It's too bad we didn't hold off on the aircraft order so we could replace everything with the neo and MAX, they run around 15% less on fuel burn than our older ones from the propaganda from Boeing and Airbus.
